  • Patent number: 6461721
    Abstract: Description of a thermo-transfer ribbon having a carrier, with a thermo-transfer color (layer) formed on one side of the carrier, and, if applicable, with additional layers, whereby the thermo-transfer color contains in addition to a coloring substance, an amorphous polymer and a wax. The thermo-transfer ribbon is characterized in that the thermo-transfer color contains a polar polyethylene wax as binding agent and an amorphous polymer, which has a mol mass weight mean Mw of more than approximately 10000 and a numerical mol mass mean Mn of less than approximately 6000. It proves itself during high energy level printing of a thermo-printer as scratch- and solvent-resistant, specifically on plastic labels.

  • Patent number: 6458449
    Abstract: An ink jet printable coating for holographic paper is presented. The coating utilizes a high dyne primer layer and a secondary layer. The secondary layer includes a plurality of microscopic pores which are preferably 1 to 6 microns in diameter. The pores are sized to allow ink jet ink to penetrate during the printing process. The coating is compatible to both water based and solvent based inks. The pores serve to provide a site to which the ink jet ink can anchor and set, thus preventing the ink from running when initially applied to the surface and speeding the rate of ink drying. Additionally, the secondary layer is porous enough to absorb the ink as it dries. The deeper the secondary layer, the further to ink can penetrate for greater adhesion to the surface and for faster drying.

  • Patent number: 6432515
    Abstract: A flexible, multilayered transfer tape is described which contains an auxiliary support, a layer of pressure-sensitive adhesive and a binder containing a white-pigmented transfer layer having greater adhesion to the pressure-sensitive adhesive layer than to the auxiliary support. The transfer layer, which contains a binder in addition to a white pigment, is present between the auxiliary support and the pressure-sensitive adhesive layer. The transfer tape is characterized in that a non-white pigment is present in finely dispersed form in either or both of a polymer-bonded interlayer and the pressure-sensitive adhesive layer. The polymer-bonded interlayer may be situated between the white-pigmented transfer layer and the pressure-sensitive adhesive layer or in the white-pigmented transfer layer itself. Such transfer tapes have significantly improved covering capacity as compared to transfer tapes in which only the white-pigmented transfer layer is tinted.

  • Patent number: 6395375
    Abstract: When a temporary adhesive layer for peelably bonding a transfer-receiving material to a thermal transfer sheet comprising a substrate film and a heat-fusible ink layer disposed on one side thereof is caused to comprise a specific adhesive, an excellent composite thermal transfer material is provided. In such a composite thermal transfer sheet, the thermal transfer sheet is firmly bonded to the transfer-receiving material so as not to cause wrinkles or deviation, both of these members may easily be peeled from each other so that the ink layer is exactly transferred to the paper in a transfer region and it is not transferred thereto at all in a non-transfer region, whereby the transfer-receiving material is not contaminated. An antistatic treatment provides a composite thermal transfer sheet causing no trouble due to charging at the time of or after printing operation.
